The building's owner Steve Burgess posted a message Saturday morning on Facebook. 

"Just wanted to take a quick second to thank all who have taken their time to message me and my family during this time. We experienced a serious structure fire to a commercial building we own downtown.

I can't thank the Fredericton Fire Department enough for what they have done and how hard they fought this blaze! And thank you to my new family at the Fredericton Police Force for keeping everyone safe so fast while the FFD fought the fire for nearly eight hours." 

Burgess said he had the three businesses in his thoughts due to the losses they suffered. 

"Mainly, no one was injured and the building after all is just a building and we will all recover in time. Thanks again friends!"
